The mangrove gerygone is a species of bird in the Australian warbler family Acanthizidae. The species is also known as the mangrove warbler. The species is thought to form a superspecies with the closely related fan-tailed gerygone of Melanesia and the Australian western gerygone. There are three subspecies of mangrove gerygone, G. l. pallida, found in southern New Guinea, the nominate race G. l. levigaster, which is found from coastal Western Australia to coastal north Queensland and is known as Buff-breasted Flyeater, and G. l. cantator, which is found from coastal Queensland to New South Wales. The species is uncommon in New Guinea and has suffered some declines due to mangrove clearances but is not considered threatened by the IUCN.
Region
Northern and eastern Australia and southern New Guinea
Typical Environment
Primarily inhabits coastal mangrove forests, from sheltered estuaries and tidal creeks to mangrove-lined bays. It forages from the mid-story to the canopy and often uses adjacent littoral scrub or paperbark fringes. In New Guinea it is patchy and uncommon compared to Australia. It avoids inland habitats and is tightly associated with saline and brackish mangrove systems.
Altitude Range
Sea level to 100 m
Climate Zone
Tropical
Ease of Keeping

Also called the mangrove warbler or Buff-breasted Flyeater, this small Australian gerygone is closely tied to coastal mangroves. It forms a superspecies with the fan-tailed gerygone and the western gerygone. Three subspecies occupy southern New Guinea and northern to eastern Australian coasts. While local declines occur where mangroves are cleared, it is currently not considered threatened globally.
Temperament
unobtrusive but active
Flight Pattern
short rapid wingbeats with quick dashes between mangrove branches
Social Behavior
Usually seen singly, in pairs, or small family parties, often moving methodically through mangrove foliage. Builds a neat, domed pendant nest with a side entrance suspended from branches. Breeding occurs in the warmer months in Australia, with both parents involved in care.
Migratory Pattern
Resident
Song Description
A series of clear, sweet whistles and thin trills, often delivered from concealed perches. Song carries well in mangrove habitat and includes repeated, tinkling phrases.
